UNITED STATES PATENT OFFICE.

EDWARD J. DOLAN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO WILLIAM HACKER, TRUSTEE, OF SAME PLACE.

CAN-ASSEMBLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 375,053, dated December 20, 1887.

Application filed November 1, 1887. Serial No. 253,979. (No model.)

. being bad to the accompanying drawings, and

to the letters and figures of reference marked thereon, which form a part of this specifica tion.

My invention relates to can-making inachinery, and has for its object to provide an attachment for machines of this kind which will facilitate the placing of the tops and hottoms upon the can-bodies while the same are in place upon the carrier during the process of manufacture.

To this end, and to such others as the invention may relate, the same consists in the peculiar combination and in the novel construction, arrangement, and adaptation of parts, all as more fully described, shown in the drawings, and then specifically defined in the claims.

In the accompanying drawings, Figure l is a plan View .of a portion of a can-making machine with my device for attaching the tops and bottoms. Fig. 2 is a side View of a canbody, showing the position of the top and bottom in first contact. Fig. 3 is a perspective view of the guides. Fig. 4 is a side view of a portion of a can inaking machine and assembling attachment with one of the guides removed. Fig. 5 is a perspective view of the guides.

Referring to the details of the drawings, A represents a section of the supporting-frame of an endless carrier for can-body blanks, the carrier proper consisting of a series of canbody clamps, B pivotally connected together to form an endless carrier for the can-body blanks, such as is commonly used in connection with can-making machinery, for conveying the unfinished can-body blanks to that portion of the machine at which the tops and bottoms of the cans are placed and afterward secured in place upon the body of the can. The form of carrier, a section of which Ihave shown, is identical in construction with the form of carrier which I have shown and described in connection with my patent, No. 371,493, of October 11, 1887. As the endless carrier, however, forms no part of my present invention, which relates solely to the can-assembling attachment, which is equally well adapted for use in connection with any of the various forms of endless carriers nsedin connection with can-making machinery, a detailed description of such carrier is deemed unnecessary in this connection. \Vithin each of the can-bodyholders B is held a can'body blank B.

Secured to the sides of the carrier-frame, and with the free ends inclined at an angle outwardly and toward the rear of the machine, are the guides O (3, each provided upon its face adjacent to the carrier with a longitudinal slot or recess, 6*, of suitable width to receive and hold the blank ends of the cans. These guides are provided at theirinner ends with extensions 0", which are arranged parallel with the line of travel of the endless carrier. The blank covers or ends, the edges of which have been turned so as to form rims to embrace the ends of the can-body, are fed by the operatorinto the recesses G at the ends of the guides O.

D is a lever, the long arm of which is pivoted to a lug or car, D, upon the outer face of the guide 0, near its point of attachment to the carrier-frame. Thelever is bentinwardly at a point near its opposite end, and its free end is passed loosely through suitable openings at the sides of the guide (I, as shown, and is held in position by means of the spring D one end of which is attached to the extension D of the lever and itsopposite end is secured to the carrier-frame, as shown.

The operation of the device is simple and will be readily understood. The tops and hottomsof the cans are placed by the operator in the recesses at the free ends of the guides O, and as each top or bottom is placed in the recess the preceding top or bottom is forced along the'recess until the same is filled along its entire length with blanks, each top or bottom, as it is forced into the end of the recess by the operator, pushing the entire series preceding it forward within the slot. As each succeeding clamp carrying a can-body blank reaches the point at which the guides O are attached to the frame, the projecting ends of the blanks are brought into contact with the forward edges of the blanks for tops or hottoms, and with the continued forward movement of the carrier the ends of the can are brought into contact with the inwardly-projecting ends of the pressure-levers D, which serve to secure the same in place.

\Vhile I have shown my-attachment as used in connection with that form of can-making machine in which the blank forming'the body of the can is carried within clamping devices secured to an endless carrier, I do not desire to limit myself to such use, as it is evident that it is equally well adapted for use in connection with any of the oanmaking machines in which endless carriers are used.

It is also evident that, instead of providing guides for placing both tops and bottoms, if for any reason it should be desired, one of the guides may be dispensed with and but a single one used.

Having thus described my invention, what I claim to be new, and desire to seen re by Letters Patent, is.-

1. The combination, with the moving canbody holder, of. an inclined ean'head guideway extending in the same general direct-ion as the travel of the can-body holder, as and for the purpose specified.

2. The combination, with the can body holder, of an inclined can-head guide for the ends, and an extension to said can-head guide arranged parallel with the travel of the canbody holder, substantially as described.

8. The combination, with the can body holder and the inclined cauhead guide for the ends, of an extension to said can -head guide arranged parallel with the travel of the can-body holder, and a presser acting on the ends, as set forth.

4. The combination, with the can body holder and the inclined can-head guide for the ends, of an extension to said can-head guide arranged parallel to the travel of the can-body holder,and a spring-actuated presser arranged to act on said ends,'as and-for the purpose specified.

5. The combination, with the can body holder and the inclined can-head guide, of an extension to said can-head guide arranged parallel to the travel of the oanbody holder, and a presser operating at right angles to the travel of the h0lder,substantially as described.

6. The combination, with the can body holder and the inclined can-head guide for the ends, of a pivoted presser located near the terminus of said guide, substantially as and for the purpose described.

7. The combination, with the can body holder and the inclined can-head guide for the ends, of a pivoted spring-actuated presser located near the terminus ofsaid can-head guide, substantially as and for the purpose specified.

8. The combination, with the can body holder and inclined canhead guide for the ends, of a presser pivoted to said can head guide and operating at right angles to the travel of the can-body holder, substantially as and for the purpose specified.

9. The combination, with the can body holder and the converging can head guides arranged upon opposite sides thereof,of pressers arranged at the termini of said guides and operating at right angles to the travel of the holder, as set forth.

10. The combination, with the can body holder and the converging can-head guides arranged upon oppositesides thereof, of springactuated pressers arranged at the termini of said guides and operating at right angles to the travel of the can-body holder, as set forth.

In testimony whereofI affix my signatn re in presence of two witnesses.
